Definitions

  • the present invention relates to a steering apparatus for outboard motors and particularly to manually operated tiller-type steering apparatus coupled directly to the outboard motor unit.
  • Outboard motors and particularly relatively low horsepower motors are constructed with a steering assembly which the operator manipulates from the rear of the boat.
  • a steering handle assembly is attached directly to the upper powerhead or drive shaft housing which, in turn, is pivotally mounted within a suitable swivel mounting bracket.
  • the vibration of the outboard motor and particularly the powerhead is transmitted to the manually grasped end of twist handle. This has been generally accepted with the effects of vibration minimized by the use of relatively soft rubber grips. Such vibration is also transmitted to the boat transom.
  • Special isolation mounting systems have been suggested but are generally employed in the larger and more expensive engines.
  • the present invention is particularly directed to a isolated mounting means for a manually operated steering unit, and in particular, provides a unitary vibration isolation coupling of the powerhead to the steering assembly and the swivel bracket assembly to minimize the transmission of vibrations from the powerhead.
  • the powerhead drive shaft housing is rotatably supported within axially spaced resilient mounts which are coupled respectively to the drive shaft housing and to a tubular steering unit rotatively mounted within a swivel bracket means.
  • the steering unit is connected to a steering handle means.
  • the resilient mounts are formed of a rubber-like material of a sufficient stiffness to transmit rotating motion of the steering arm and unit to the drive shaft housing for steering of the outboard motor while effectively isolating the powerhead and drive shaft housing from the steering mechanism and the supporting swivel bracket means.
  • the swivel bracket includes a split tubular element within the steering arm pivot support and drive shaft housing are assembled.
  • the split unit permits convenient assembly of the various components.
  • the steering arm assembly includes a steering arm unit having a pivot support with upper and lower coupling bearing members with the upper member having an interconnected, outwardly extending steering arm.
  • the upper and lower connecting bearing units are also formed as split members with the outer portion defined by a pair of separate spaced clamping cup or cover members.
  • the drive shaft housing is formed with a generally tubular extension of a length generally corresponding to the length of the steering arm pivot support.
  • the steering arm support is clamped about the drive shaft housing with an upper and lower annular mount located between the steering bearing units and the corresponding portions of the drive shaft housing, with mounts coupled to the housing and bearing units by complementing, mating slots and projections.
  • the annular rubber mounts are formed with a first pair of axial slots formed in diametrically opposite sides of the mount and projecting inwardly from one end. A similar pair of slots offset by 90° from the first set of slots and extending inwardly from the opposite end of the annular mount.
  • the drive shaft housing and the arm bearing are provided with correspondingly offset projections adapted to mate with the slots in the annular mounts.
  • the assembly is clamped within a split tubular member of the swivel bracket assembly with upper and lower sleeve type bearings located between the steering bearings and the swivel bracket tubular members.
  • the sleeve bearings are preferably formed with outwardly projecting flanges providing thrust bearings between the ends of the tubular unit of the swivel bracket and the steering arm bearings.
  • a clamping co-pilot band may be located about the upper sleeve bearing unit to permit adjustable clamping pressure on the upper bearing unit for holding of the motor in any given position.
  • the drive shaft housing is employed as the exhaust passageway for discharging of the exhaust gases outwardly through the lower unit.
  • the lower end of the exhaust tube may be essentially closed off and an idle relief passage is preferably provided to permit escape of the exhaust gases.
  • the drive shaft housing is provided with an opening permitting the exhaust gases to pass outwardly through the chamber between the steering support member and the outer or aft wall of swivel bracket assembly. An opening is provided in the aft wall to allow the exhaust gases to pass into a tuning passageway for discharge to the atmosphere.
  • the outer swivel wall is provided with a generally U-shaped passageway with a closed end aligned with the exhaust opening and extending upwardly and then downwardly to discharge exhaust gases downwardly toward the water.
  • the combination of the internal expansion and baffle chambers provided by the concentric steering support and the drive shaft housing assembly with the extended tuning passageway permits significant tuning of the exhaust system at idle to thereby minimize the sound of the exhaust gases.
  • the volume of the chamber and the length and cross section of the tuning passageway are selected to provide a tuned characteristic generally similar to that described in the co-pending application of Joseph H. Harralson et al. entitled “Exhaust Relief Silencing Apparatus for Marine Propulsion Systems" filed on Aug. 26, 1974 with Ser. No. 500,634 and assigned to the assignee of this application.

  • the drive shaft housing 5 defines an exhaust chamber 22 extending downwardly to the lower end of the unit 6 where the exhaust gases of the engine 4 are discharged, preferably through the propeller unit 6 in accordance with any known or desired construction. During engine idle operation, exhaust gases may be trapped within chamber 22.
  • the drive shaft housing 5 is provided with a pair of aligned openings 23 and 24 generally centrally of the length of the cylinder 14 to permit discharge of exhaust gases therefrom under idle conditions.
  • the exhaust gases passed outwardly of the section 14 and through a generally tortuous assembly path within the section 9 and particularly through an idle exhaust tuning section 26 secured to the aft or back side of the assembly 9, as more fully developed hereinafter to reduce the noise level under idle conditions.
  • the cylinder 14 of the drive shaft housing 5 is coupled through the assembly 9 to the tiller handle 13 which is pivotally connected to the arm 12 by a suitable pivot connection 28.
